ISL43L210
Ultra Low ON-Resistance, +1.1V to +4.5V
Single Supply, SPDT Analog Switch
The Intersil ISL43L210 device is a low ON-resistance, low
voltage, bidirectional, single pole/double throw (SPDT)
analog switch designed to operate from a single +1.1V to
+4.5V supply. Targeted applications include battery powered
equipment that benefit from low on-resistance and fast
switching speeds (t
ON
= 7ns, t
OFF
= 3ns). The digital logic
input is 1.8V CMOS compatible when using a single +3V
supply.
Cell phones, for example, often face ASIC functionality
limitations. The number of analog input or GPIO pins may be
limited and digital geometries are not well suited to analog
switch performance. This part may be used to “mux-in”
additional functionality while reducing ASIC design risk. The
ISL43L210 is offered in a 6 lead SC70 package, alleviating
board space limitations.
The ISL43L210 is a committed SPDT that consist of one
normally open (NO) and one normally closed (NC) switch.
This configuration can also be used as a 2-to-1 multiplexer.
